Details/Specifics of Change:
SOCC has reported re-occurance of the barcode pattern in the AVHRR imagery
for NOAA-16. Once again a MIRP rephase will be required.. the rephase will
occur at the implementation times indicated in the attached schedule...
Please find attached a schedule of the rephasing to occur over the next 3
Users will see scan line drop outs when the rephase occurs. Checking "bit
1: resync occurred on this frame" in the data record quality indicators will
tell you when the rephase occurs. "bit 29: data gap precedes this scan"
indicates the gap created by the rephase in the scanline after it occurs.
Any user feedback on the improvement (or lack of) in AVHRR imagery
following the rephase would be greatly appreciated.
Thank you for your support.
